Artwork: Corot

In a survey from ARTnews, experts were asked to name the most faked artists of all time. Almost every expert cited the 19th century Barbizon landscape painter Jean-Baptiste-Camille Corot, whose work has been knocked-off so frequently that jokes about Corot's impossibly prolific production have run in print since 1940. In 1990, Time magazine said: "It used to be said that Corot painted 800 pictures in his lifetime, of which 4,000 ended up in U.S. collections."

Other frequently faked artists, according to that same survey, include Vincent van Gogh, Salvador Dali, and Auguste Rodin.
